Specification form ng part of Letters Patent No. 56,6] 7, dated July 24, 1866.

To all whom t may concern:

Be it known that I, Gritos W. SALADEE, of

Newark, county of Licking, State of Ohio, have invented a new and Improved Mode of Gonstructing Padlocks 5 (Gase F and I do hereby declare that the followng is a full and eX- actdescription thereof, re ference being had to the accompanying drawings, and to the letters of reference marked thereon The nature of my invention consists, first, in that of combining with the shield-plate N of the lock a guard-ring, O, by which to prevent reaching the sprin.,r S, or any part of the tumbler A in front of the shield-plate, by any burglar 'instrument which may be introduced through the key-hole f )r the purpose of picking the lock; second, in that of making an indentation, X, in the top of the tumbler A, as a substitute for the ordinary key-stud, and into which is made to work the pivot R on the end of the key, whereby I am saved the expense of providing the key-stud and of drilling the corresponding hole in the key; third, in that of placing the stud I on the tumbler A, in combination with the slot O .through the shield-plate, for the purpose of operating the tumbler; and, fourth, in that of making the spring S into the shape of a true circle, by which peculiar form it is made to operate more directly against the hasp and tumbler than any other form that can be devised for a single spring designed to act in the double capacity here shown.

In the drawings, Figure l is a front view 0f the look with the lid removed, showing the complete working parts of the same. Fig. 2 is a view of the lower end of the key, showing the pivot It, which operates in the indentation X of the tumbler A.

The tumbler A of this lock is substantially the same as the one shown in my applications O and E, and is operated by the same kind of spring 5 but the manner here shown of operating the tumbler with the key is radically different from either of my former applications. To this tumbler I secure the stud I, and which is made to pass through the slot O of the shield-plate N, so that the key of the lock may drop into the slot and take hold of stud I, and thereby force the hook end of the tumbler A (represented by the blue shading and black dotted lines) back out of the eye in the end of the hasp In the center of the tumbler A, I countersink or drill an indentatiou,.X, and on the end of the key, Fig. 2, I turn a corresponding pivot, R, which indentation X and pivot R serve to hold the key upon its center when in the lock, the same as if the ordinary key-stud` were set in the back of the lock and the usual corresponding hole drilled in the key. It is a noticeable fact that the key of all common padlooks as now made, milled, and drilled, and with a corresponding stud set in the lock for the key to work on, is in many cases more than equal to one-half the whole cost of the lock.

In this combination of the pivot It of the key, Fig. 2, with the indentation X in the tumbler A, I have in view the manufacture of a key for padlocks, equally efficient and practical in its operations as any of the ordinary class now in use, at less than one-half the cost now attending the production of the same class of key on the old plan.

l cover this tumbler A with the shield-plate N, and on the top of this I secure the guardring O, within which is the slot O, stud I, and the usual number' of wards. This ring O is made high enough to lill up the space between the top of the shield-plate and the inside surface of the cover or front plate of the lock.

The novelty and advantages I here claim are, that the guard-ring and such number of wards as are usually placed in the back of the old-style locks are all secured to the shieldplate and made part thereof, thereby admitting of casting the shield-plate, guard-ring, and Wards in one piece, thus greatly simplifying the lock in its manufacture, and in a corresponding degree diminishing the cost of the same.

The spring S, here shown, I bend into a true circle, and which I have found by experimenting is the only form proper for a single spring the ends of which are designed to act in opposite directions, the one to lock the tumbler and the other to throw up the front end of the hasp D.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The shield-plate N, provided with the guardrin g O, and otherwise constructed in the inanner and for the purpose substantially as shown and described.
